1. Wintertime design situations and specifications
For putty powder design, a qualified basic layer has five simple attributes: organization, smooth, free of moisture, fairly neutral and clear. For your construction situations of putty powder, the construction atmosphere heat needs to be handled above 5°C as well as the ambient moisture must be operated within 85undefinedPercent, usually building is not really made it possible for.
2. Design conditions and specifications of putty powder
For the construction of internal and external wall structure putty powder, some tasks still have to be constructed if the temperatures is below 5°C in the winter months because of design period needs. To be able to boost the design high quality, these matters needs to be mentioned while in development:
(1) Base level inspection and therapy
Foundation level therapy is the basis of layer engineering. The material of bottom layer treatment method consists of: getting rid of dust, oils unsightly stains and loose supplies at first glance of the bottom covering decreasing or removing work surface flaws boosting the physical or chemical attributes of your top of the basic level.
(2) Putty design
For the construction of the finish system, the substrate needs to be dry as well as the wall surface work surface temperatures should be made sure prior to construction in winter. As soon as the daytime temperatures is below 5 levels, try to construct in the wall surface under sunshine. The night time temperatures needs to be above levels Celsius, or else it cannot be constructed to prevent the putty covering from cold.
(3) Grinding putty and judging the drying out issue
The putty must be completely dry prior to mincing, so as to ensure that the putty does not stick to the sandpaper while in grinding. The top flatness management must also be performed after it can be completely dried out. When the putty is not really free of moisture or frozen, the putty will keep to the sandpaper in the course of milling, and the work surface is tough to grind nicely.
(4) Coating building
Coating construction: Before coating, it is required to confirm the substrate is utterly dried up. The building temperatures of water-undefineddependent surface finishes ought to be managed above 5°C. During the drying and motion picture-undefinedcreating approach, if the temperatures is below absolutely no, the emulsion will lock and get rid of its bonding and motion picture-undefinedcreating impact. Consequently, it is needed to ensure the minimum temperatures throughout the motion picture-undefinedcreating and drying out method is just not below 0°C.
(5) Color storing
Paint stored on location during winter must be labeled and loaded inside to ensure the inside heat is above 0℃. When it is below 0℃, heating system or electrical heating should be used to retain the inside temperature. Open flames are strictly forbidden to heat the indoors heat. Seldom used painting while in building ought to be placed indoors, and freezing merchandise really should not be applied.
(6) Color film routine maintenance and finished product security
The drying out duration of the color video on the surface of the item is one week in a normal temperatures of 25℃. Because of the generally reduced ambient temperatures from the covering building during winter, the drying out and achieving common time of the painting film must be relatively prolonged. During this period, the pollution and bruises on the color movie surface area needs to be minimized in order to avoid influencing the entire outcome from the restoration because of air pollution and bruises. In the wintertime, correct protective steps should be considered in line with the on-site building situations to protect yourself from very cold from the covering movie and be sure the smooth development from the task covering high quality and development improvement.
